AI Technical Summary

Benefits of technology

The solution enables a compact, portable, and versatile breathing assistance device that maintains safety and reliability, allowing for various respiratory modes without duct size constraints, and ensures patient safety even with a disabled gas source by maintaining airflow.

Problems solved by technology

This configuration results in a high breathing resistance, which increases the work of breathing for the patient.
This increases the complexity of the controller 25 of the respirator.
In some respiratory modes, the expiratory valve 22 has to be operated as much as possible in real time, which is quite difficult in such expiratory valves because of the pneumatic inertias which are associated with them.
The requirement for such large diameter ducts is an obstacle to miniaturization of the device, particularly the breathing circuit.
And here again, such large duct diameters is an obstacle to miniaturization.

Embodiment Construction

[0054]The following description is provided in relation to several embodiments which may share common characteristics and features. It is to be understood that one or more features of any one embodiment may be combinable with one or more features of the other embodiments. In addition, any single feature or combination of features in any of the embodiments may constitute additional embodiments.

[0055]In this specification, the word “comprising” is to be understood in its “open” sense, that is, in the sense of “including,” and thus not limited to its “closed” sense, that is the sense of “consisting only of ” A corresponding meaning is to be attributed to the corresponding words “comprise”, “comprised” and “comprises” where they appear.

[0056]The term “air” will be taken to include breathable gases, for example air with supplemental oxygen. It is also acknowledged that the blowers described herein may be designed to pump fluids other than air.

Abstract

A breathing assistance device includes a gas regulating valve (1300). The gas regulating valve is operated by a linear actuator (1330). The linear actuator may include a movable member that moves an obstruction member between an open position and a closed position. The linear actuator is isolated from a gas flow path through the valve.

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation application of U.S. application Ser. No. 13 / 377,244, filed Dec. 9, 2011, now allowed, which is the U.S. national phase of International Application No. PCT / AU2010 / 000708, filed Jun. 9, 2010, which designated the U.S. and claims the benefits of U.S. Provisional Patent Application Ser. No. 61 / 185,250, filed Jun. 9, 2009, the entire contents of each of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a breathing assistance device, and more specifically, to a linear actuator that is used in a gas regulating valve of a breathing assistance device.BACKGROUND OF THE INVENTION[0003]A variety of breathing assistance devices, which we will also generally refer to as “respirators” in this text, are available today. These respirators are equipped with a source of respiratory pressurized gas. They are generally referred to as “autonomous” because an external pres...
